Polypropylene staple fiber is a specially treated polypropylene monofilament, which meets the requirements of clean and environmental protection of high-tech materials in today's society. It is made of pure polypropylene, non-toxic and harmless, and has anti-alkaline, acid-proof and non-absorbent properties. It is completely resistant to corrosion and is a highly durable reinforcement material.

Polypropylene staple fiber can be roughly divided into non-woven fabrics, home textiles, diapers and the like according to the use, among which the non-woven fabrics with a large production volume account for more than 70% of the total products. In 2017, fiber accounts for about 11% of the downstream demand for polypropylene. It is widely used in non-woven fabrics, apparel fabrics, carpet yarns, medical surgical products, and sanitary products.

The non-woven fabric industry is currently developing rapidly and is considered to be an industry in the 21st century. With the full liberalization of China's second-child policy, the demand for maternal and child products such as wet wipes and diapers will continue to grow. The continued development of non-woven fabrics will drive the development of polypropylene staple fibers to a certain extent, especially at present. The demand for medical grade non-woven fabrics is also on the rise.
